Lab-Grown Diamond Engagement Ring

Sunlight catches the sharp edges of a 4 x 4 mm square diamond, its facets whispering quiet brilliance across a warm 18K yellow gold band. This five-stone semi-set invites you to choose a center stone that will anchor a story of subtle geometry and gentle light.

Crafted in Williamsburg, the band’s smooth finish and low-profile setting ensure a comfortable fit for everyday wear, while the delicate arrangement of side stones adds a refined rhythm to the silhouette. Each curve and angle is carefully inspected to meet exacting standards of polish and balance.

Our diamonds are lab-grown, offering clarity and sparkle with a mindful approach to sustainability and ethical sourcing.

Designed for those who appreciate architectural elegance softened by warmth, this ring complements slender fingers and pairs effortlessly with stackable bands or a wedding band. Its modest height slips easily beneath gloves or sleeves, making it a seamless companion to daily life.

Should you need adjustments, resizing is available to ensure the ring fits as naturally as it feels.
